As the moving plate moves, the sleeve is fitted onto the positioning pin on the frame.

Similarly, when the frame is not placed in the correct position, the second guide shaft on the first inspection pin will retract.

[0017] 2. In this invention, when the vehicle frame is placed on the workbench, the third cylinder pushes the first clamping plate to move. The movement of the first clamping plate facilitates the sliding of the first driven rod, increasing the stability of the movement of the first clamping plate and facilitating the clamping and fixing of the vehicle frame by the first clamping plate. Then, the fourth cylinder pushes the second clamping plate to move. The movement of the second clamping plate also moves the second driven rod, thereby facilitating the clamping and fixing of one side of the vehicle frame by the second clamping plate. Then, the fifth cylinder pushes the docking plate to move, facilitating the sliding of the second slider on the second guide rail, facilitating the movement of the second top plate to the top position of the vehicle frame. Then, the sixth cylinder pushes the lifting plate to move downward, facilitating the insertion of the second inspection pin into the hole at the top of the vehicle frame. When the vehicle frame is in place, the third guide shaft will retract, and the second proximity switch can detect it in time.

[0018] 3. In this invention, when the frame is placed on the workbench, the seventh cylinder operates to facilitate the insertion of the third inspection pin into the hole at the bottom of the frame. Then, the eighth cylinder pushes the limiting plate to move to the side of the frame, and the third limiting plate is inserted into the hole on the side of the frame, thus facilitating the positioning of the frame. The fourth bracket operates to push the driven plate to move, facilitating the movement of the control frame to the top position of the frame. Then, the tenth cylinder pushes the fifth bracket downward to facilitate the insertion of the fifth inspection pin into the hole at the top of the frame, thus facilitating the detection of the frame's position.

[0042] The working principle of this invention is as follows: The frame is placed on the workbench 1, and then the first slider 205 slides on the first slide rail 204, which facilitates the movement of the moving plate 206 to one side of the frame. As the moving plate 206 moves, the sleeve 215 is fitted onto the positioning pin on the frame. When the sleeve 215 and the positioning pin on the frame are not on the same axis, the sleeve 215 will push the first guide shaft 212 to retract, which facilitates the first detection disc 213 to disengage from one side of the first proximity switch 214. The first proximity switch 214 will be electrically connected to the alarm unit through the wire to remind the operator that the frame is not placed in the correct position. As the frame is placed, the first inspection pin 309 will be inserted into the hole at the bottom of the frame through the second spring 308. Similarly, when the frame is not placed in the correct position, the second guide shaft 306 on the first inspection pin 309 will retract.

[0043] When the frame is placed on the workbench 1, the third cylinder 402 pushes the first clamping plate 403 to move. The movement of the first clamping plate 403 facilitates the sliding of the first driven rod 404, increasing the stability of the movement of the first clamping plate 403 and making it easier for the first clamping plate 403 to clamp and fix the frame. Then, the fourth cylinder 407 pushes the second clamping plate 408 to move. The movement of the second clamping plate 408 also moves the second driven rod 409, making it easier for the second clamping plate 408 to clamp and fix one side of the frame. Then, the fifth cylinder 507 pushes the docking plate 505 to move, making it easier for the second slider 504 to slide on the second guide rail 503, making it easier for the second top plate 510 to move to the top position of the frame. Then, the sixth cylinder 511 pushes the lifting plate 512 downward to move, making it easier for the second inspection pin 519 to be inserted into the hole at the top of the frame. When the frame is in place, the third guide shaft 514 will retract, and the second proximity switch 516 can detect it in time.

[0044] When the frame is placed on the workbench 1, the seventh cylinder 606 operates to allow the third gauge pin 607 to be inserted into the hole at the bottom of the frame. Then, the eighth cylinder 612 pushes the limiting plate 610 to move to the side of the frame, and the third limiting plate 616 is inserted into the hole on the side of the frame, thus facilitating the positioning of the frame. The fourth bracket 603 operates to push the driven plate 702 to move, allowing the control frame 705 to move to the top position of the frame. Then, the tenth cylinder 706 pushes the fifth bracket 707 downward to allow the fifth gauge pin 714 to be inserted into the hole at the top of the frame, thus facilitating the detection of the frame's position.
